Feces is
added to the sample device and mixed with a flotation media (zinc
sulfate solution is recommended). The device filter is seated into the
device. Additional solution is added to create a positive meniscus. A
microscope cover slip or slide is placed on top of the device and
allowed to incubate for 5-10 minutes, depending on the time required by
the solution used. Parasitic ova and, in the case of zinc sulfate
solution, Giardia cysts adhere to the cover slip or slide surface. The
cover slip or slide is examined microscopically for the presence of
parasitic material.• 35% more filter area for improved detection of low-level ova burdens• Specially designed filter frees up and floats even more parasitic material and locks into place to prevent leaking
